Preparation of waste paper fiber-reinforced biodegradable polybutylene adipate terephthalates (PBATs) and their feasible evaluation for food package films with high oxygen barrier and antistatic performances.

• A modified PBAT pellet with qualified physical performances has been manufactured by appropriate prescription. • A waste paper fiber-reinforced PBAT composite film has been manufactured with the modified PBAT pellet, T-Die extrusion, and blade-coating process. • Lab-made modified PBAT film D exhibits excellent physical characteristics. • The feasibility of food package with lab-made modified PBAT film D has been evaluated. • Lab-made modified PBAT film D is a highly potential food package film. With polyethylene glycol-modification of waste paper fiber as the hydrophilic enhancer and prescription of polybutylene adipate terephthalate as well as antistatic agent/processing aid, a food package film with great transparency, good antistatic property, and high oxygen barrier capability have been prepared by T-Die extrusion and blade-coating procedure. To evaluate its feasibility for food package, the prototype of food container has been also manufactured, eventually examining its anti-corrosion capability for the milk. Experimental results elaborate that lab-made food package film can efficiently obstruct the entry of oxygen in the air into the food container, consequently dramatically extending the expiration date of milk.
